SATA HD Performance issues on new build

[Vindicis]

I'm getting some odd/poor performance from a new build with an WD6401AALS. My spec's are:

Intel Core i7-860
Gigabyte GA-P55M-UD2
Kingston 2GB PC3-10600 x 2
Windows 7 Ultimate x64

I've updated all the drivers and set the following options in the bios:
SATA RAID/AHCI Mode = AHCI
SATA Port0-3 Native Mode = Enabled
Onboard SATA/IDE Device = Enabled
Onboard SATA/ED Ctrl Mode = AHCI
The drive is plugged into SATA 0 and not GSATA0

Is there anything I messed up or something I'm missing? Any help would be greatly appreciated!

Since the drive is also the OS/Boot drive, I don't see anything wrong. Even if you, the user, are not doing anything disk intensive, Windows will have things going on the background which will cause those dips in HDTune. Your WEI score is normal. Mechanical drives can't score any higher.
